HENRY W. HATHC'BN, OF REASON CITY, IOWA.

OIL BURNER.

Application filed June 8,

To all whom it may concern:

Be it known that I, HENRY W. HATHORN, a citizen of the United States, residing at Mason City, in the county of Cerro Gordo and State of Iowa, have invented new and useful Improvements in Oil Burners, of which the following is a specification.

This invention relates to improvements in oil burners and has for an object the provision of a burner wherein the fuel will be quickly converted into a gaseous state to provide and maintain a hot flame.

To this end, the invention includes a novel form of generating chamber, arranged so as to increase the surface exposed to the flame and provide a spreader therefor, so that the flame will be distributed over the entire heating surface and provide a highly combustible gas.

The invention further includes means whereby the fuel will be fed to the generating chamber in the form of an even spray, so that it may be distributed over the walls of the chamber and more quickly converted into gas.

With the above and other objects in View, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a side elevation of a burner constructed in accordance with the invention.

Figure 2 is a top plan view of the same.

Figure 3 is a vertical sectional view on the line 33 of Figure 2.

Figure 4; is a sectional view on the line H of Figure 2.

Figure 5 is an enlarged section illustrating the structure of the generating chamber fuel feed.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a base which is preferably supported upon legs 11 and which is designed to support a hollow casing 12.

The interior of this casing provides a gas generating chamber 13 which is herein shown as of a round relatively flat form. This casing is supported from one end of the base by means of a fuel feed pipe 14, the

latter being connected with the casing by means of an elbow 15, one end of which is threaded into a nipple 16 extending from one wall of the casing. The end of the elbow which enters the nipple 16 is provided with a restricted fuel inlet port 17 so that when the chamber 13 is heated the fuel will pass through this port in the form of spray and the latter will strike the highly heated walls of the generating chamber and g1: quickly converted into a highly combustie gas.

Extending from the opposite side of the generating chamber is a pipe 18 which extends downwardly and communicates with one end of a horizontally disposed pipe 19, the last mentioned pipe being located between the base 10 and the generating chamber 13. This pipe 19 is closed at its free end and is provided with a gas escape port 20 so as to provide a burner.

The bottom wall of the generating chamber 13 is substantially cone-shaped, the cone being inverted so as to position its point- 21 immediately above the gas escape port 20, so that the flame from this port will strike the point 20 and be distributed and deflected by the bottom wall of the generating chamber. In addition to acting as a distributor, this bottom wall will increase the heating surface of the chamber so that a relatively large quantity of gas will be generated and the burner maintained at a high state of eificiency.

Formed in the base 10 is a pan 22 which is designed to receive a suflicient quantity of oil for initially heating the burner at the beginning of its operation.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is An oil burner comprising a base, a relatively fiat hollow generating chamber spaced above the base, a feed pipe connecting the base and generating chamber for supporting the latter, a nipple spacing the feed pipe and generating chamber respectively and having a restricted fuel outlet port within the chamber, a downwardly extending pipe connected at its upper end to the opposite side of the generating chamber and connected at its lower end to a horizontally disposed burner pipe located between the base and generating chamber, said burner pipe having its free end closed and a gas escape port in the top and adjacent the center thereof, an inverted substantially cone-shaped lower-wall for the generating chamber, the point of the cone being positioned directly above the escape port of the burner pipe, said lower Wall increasing the heating surface and defining a flame spreader, and an oil pan provided in the base beneath the burner pipe.

In testimony whereof I aifix my signature.

HENRY W. HATHORN.
